Kerrigan -- Hope and Vengeance #0 is a relatively short comic, but the art and writing is top-notch. And here's the kicker -- it's absolutely free. You don't have to pay for the comic, you simply plunk it in your cart, checkout and read. The comic is a fairly brisk 8 pages, but with a story by Cameron Dayton and some really stunning art by Zoddd, not to mention the absence of a price tag, this is a nice treat for StarCraft fans.
To my knowledge, this is the first time Blizzard's ever offered a free digital comic of this scope. And it does make one wonder.
